It's difficult to see and comment on these videos due to the lack of light and then not having them rotated properly creates some additional issues. But from what I can see, you suffer an issue that many of us amateurs have. Which is early extension (standing up) or losing inclination to the ground before impact.
You can see how much you have stood up before impact. Look how high your hands are - and how you have lost nearly all of your waist bend / spine angle before you hit the ball.
Interesting... I have never looked at it that way. Is there any sort of swing thought or drill to work on to help this?
Would this start from taking the club back to far inside?
When you refer to "Look how high your hands are", is this referring to at impact?
Look at the shaft angle at address (A1) versus in the third frame right before impact (A6.9). The shaft is much - MUCH more vertical at A6.9. The reason is that you are standing up - before you impact the ball - also commonly called:
a.) Early Extension
b.) Not maintaining your Spine Angle
c.) Losing your inclination to the ground
In order to maintain your inclination to the ground - you need to slide your hips. Watch this video:
I selected this video above as it does a fair job of showing you what you are doing currently (thrusting your hips) instead of what you need to do to impart better - more consistent contact on the ball (slide your hips).
Also, here is an interesting drill from Andrew Rice - which shows how to slide the hips into impact. You can clearly see the move is sliding the hips toward the target (or into the ball - pushing it into the wall).
***Make sure that when you do this - you keep your head steady. Don't let your head move laterally side to side. It should stay still. This will ensure you are getting secondary axis tilt which is important to hit solid golf shots.***
PS. I say A6.9 above because A7 is actually at impact - when the clubface impacts the ball. But with your video given it is 30fps - it is hard to stop the camera right at A7. I was only able to get it to stop just before impact and see the shaft (lots of blur). The 30fps cell phone cameras can work - but you need better lighting. The lighting, or lack of lighting in your videos makes it difficult to see the club.
Sorry for throwing so much into this response... But I hope it helps clarify what I was talking about. If you have additional questions, let me know. I'll try and help you the best I can. Note, you have some decent mechanics already, so I think with some work, we could get you scoring better.
